LOCK.

To all whom it may concern:

'Be it known that I, JONATHAN VVnNcnRn, citizen of the United States, residing at Dalton, in the county of YVayne and State of Ohio, have invented certain new and useful Improvements in Locks, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in looks, and has relation more particularly to a device of this general character of a permutation type, and wherein rotary tumblers are employed, and it is an object of the invention to provide a lock of this class having novel and improved means whereby the requisite endwise movement is imparted to the bolt.

It is also an object of the invention to provide a novel and improved lock of this character whereby the bolt is effectually held against retrograde movement when extended, together with means movable in a direction substantially at right angles to the bolt for releasing the same and permitting retraction of the bolt upon rotation of the last named means.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my im proved lock whereby certain important advantages are attained and the device ren dered impler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view in elevation of a lock constructed in accordance with an embodiment of my invention, and with the bolt extended Fig. 2 is a sectional view taken substantially on the line 22 of Fig. 1;

Fig. 3 is a view in elevation of one of the tumblers or disks as herein embodied;

Fig. 1 is a view in elevation of the inner end of the spindle as herein employed;

Fig. 5 is a view in elevation of the inner. side of the bolt; and

Fig. 6 is a view in elevation of the inner end of the second rotary tumbler comprised herein.

As disclosed the accompanying draw Serial No. 284,543.

ings, C denotes a casingof requisite dimensions and configurations and which is provided in a side or edgewall with an opening 1 through which the bolt Bis movable.

A side face of the casing C is provided with an inwardly directed annular flange 2, and said side face of the casing at the axial center of the chamber defined by said flange 2 is provided with an inwardly directed finger or pin 3.

4 denotes a tumbler or disk which has its peripheral portion in contact with the inner tion 7 opposed to the tumbler or disk 4 is provided with an annularly directed groove or channel 9 substantla'lly concentric to the inner end portion of the slot- 8, and a portion 10 of said channel 9 to one side of the slot 8 is enlarged toward the inner end of the slot 8 and said enlargement comprises substantially a segment of ninety degrees, so that a straight shoulder 11 is arranged at the inner end of the slot 8 and substantially at right angles to the longitudinal axis of said slot. The groove or channel 9 is not continuous, but has its end portions terminating in close proximity one to the other but slightly separated, so that a second shoulder 12 is also provided.

Interposed between the portions 7 0f the bolt Band the second or front face of the casing C is a second rotary tumbler 14 pro- In the present embodiment of my invenf tion the opening 15 comprises the bore of a bushing or sleeve 18 disposed axially through the tumbler 1 1 and suitably engaged therewith so that Said bushing or sleeve 18 is substantially an integral part of the tumbler 14. The bushing 18 has its outer end portion extended beyond the front face of the casing C and terminating in a disk 19, and which disk 19 has its peripheral portion provided with the identified gradu ations 20 coacting with an annular series of identified graduations 21 produced on the outer surface of the front face of the casing U, and which is particularly illustrated in Fig. 1. Disposed through the opening 15 of the tumbler i and the inner end portions of the openings 5 and 8 is a spindle 22. The inner end of the spindle 22 is provided with a socket 23 to receive the finger or pin 3 and the opposite end portion of the spindle terminates outwardly of the disk 19, and suitably secured to the extended portion of the spindle 22 is an operating member 24 whereby endwise or rotary movement may be imparted to the spindle 22. The inner end portion of the spindle 22 is provided with a laterally directed wing 25 of a configuration conforming to the inner portions of the slots 5 and 8 and the enlarged portions 6 and 6 thereof, so that when said slots 5 and 8 are in register, endwise move ment may be imparted to the spindle 22.

The inner face of the tumbler let in radial alinement with the opening 15 thereof is provided with a pocket or recess 26 of a depth to completely receive or house the spheral member 27. The enlarged portion 6 of the slot 8 is also of a size to readily receive the member 27 when the recess or pocket 26 is brought into register therewith, and in order to assure the seating of the member 27 within said enlarged portion of the slot 8, I interpose between the inner end of the recess of pocket '26 and the member 27 an expansible member 28 herein disclosed as a coil spring. It is also to be noted in Fig. 2 that the bolt B or more particularly the portion 7 thereof is of such thickness that the member 7 is completely house-d or received within the portion 6 of the slot 8. hen the member 27 is within the portion 6 of said slot 8 it will be impossible to retract the bolt B.

The inner face of the wing 25 at its outer end is provided with an upstanding finger or tongue 29 which is adapted to ride within the groove or channel 9 hercinbefore re-. ferred to, to extend or retract the bolt B as will be hereinafter set forth.

As illustrated in Fig. 2, the bolt B is shown extended with the tumblers 4 and 14 in proper adjustment relative to the slot 8 of the bolt B,,and to retract the bolt B it is only necessary to pull the spindle 22 outwardly, which will result in the mean ber 27 being received within the recess or pocket 26 and the finger or tongue 29 extending within the groove or channel 9. The tumbler 14 is then rotated to carry the member 27 away from the slot 8 and the spindle 22 moved longitudinally to the limit of its inward movement. With the spindle in this position rotation is imparted thereto toward the right, which brings the finger or tongue into contact with the shoulder 11 so that inward movement will be imparted to the bolt B. Rotary movement may then be imparted to the tumbler 14.- through the medium of the disk 19 so that the moving of the bolt B into extended position may be made more dilii cult.

When it is desired to extend the bolt B the tumbler 11 is adjusted in accordance with the desired combination and as determined by the identified graduations 20 and 21 until the pocket or recess 26 is properly positioned. The spindle 22 is then rotated with the operating member or head 24 serving as an index acting in conjunction with the identified graduations 21 to properly position the wing 25 and also the slot 5 of the tumbler or disk 4:. This movement of the spindle 22 results in the forward movement of the bolt B so that at the proper moment the member 27 will be received within the enlarged portion 6 of the slot of the bolt B whereby said bolt B is effectively main tained against retraction. The spindle 22 may be further rotated so that the same will not be properly set to efiect retraction of the bolt. It will also be self evident that the contact of the finger or tongue 29 with the forward wall of the groove or channel 9 will result in the forward or extended movement of the bolt B.

From the foregoing description, it is thought to be obvious that a lock constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
